Detailed Implementation

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] This utility model provides an anti-theft backpack that uses magnetic attraction to seal the opening, preventing the backpack from being opened with sharp objects, effectively ensuring the safety of the items stored inside. Please refer to [link / reference]. Figure 1-2 It includes: backpack assembly 100, power switch 200 and back panel assembly 300;

[0045] Example 1

[0046] Please see Figure 1 The backpack component 100 includes a bag body 110, a front pocket 120, a first top cover 130, and a second top cover 140;

[0047] The left and right sides and bottom of the front pocket 120 facing the bag body 110 are sewn to the front surface of the bag body 110. The top surface of the front pocket 120 facing the bag body 110 is open to the front surface of the bag body 110. Items can be placed in the space between the front pocket 120 and the bag body 110 through the opening. A magnetic attraction device is provided between the top surface of the front pocket 120 facing the bag body 110 and the front surface of the bag body 110 to seal the front pocket 120 and the bag body 110.

[0048] The first top cover 130 and the second top cover 140 are sewn together at the top opening of the bag body 110. A magnetic attraction device is provided between the first top cover 130 and the second top cover 140. The magnetic attraction device can fix the first top cover 130 and the second top cover 140 together to seal the top opening of the bag body 110.

[0049] The backpack's openings are sealed magnetically. Since the magnetic seals do not have the teeth of a zipper, outsiders cannot force the zipper open by inserting a sharp object into the teeth, thus effectively improving the backpack's anti-theft performance and ensuring the safety of the items stored inside.

[0050] Example 2

[0051] Please see Figure 1-9 A rechargeable battery is detachably installed inside the cavity of the package body 110;

[0052] The front surface of the package 110 has a first magnetic groove 110a at the top, and a first magnetic metal sheet is glued into the inner cavity of the first magnetic groove 110a. The rear surface of the package 110 has a mounting hole in the middle, and a first conductive sheet 110b is embedded in the mounting hole. The first conductive sheet 110b is electrically connected to the rechargeable battery.

[0053] A first electromagnet 120a is glued to the top of the front pocket 120, corresponding to the position of the first magnetic groove 110a facing the top of the bag body 110;

[0054] The first electromagnet 120a is matched with the first magnetic slot 110a. The first electromagnet 120a can be inserted into the inside of the first magnetic slot 110a and contact the first magnetic metal sheet. After the first electromagnet 120a is energized and magnetized, it attracts the first magnetic metal sheet and fixes the first electromagnet 120a inside the first magnetic slot 110a, thus sealing the opening between the front pocket 120 and the bag body 110. Due to the strong magnetic attraction, without demagnetization, a small external force cannot pull the first electromagnet 120a out from the inside of the first magnetic slot 110a. At the same time, since the first electromagnet 120a is inserted into the inside of the first magnetic slot 110a and contacts the first magnetic metal sheet, even a sharp object cannot pry it open between the first electromagnet 120a and the first magnetic metal sheet. This effectively improves the anti-theft performance of the backpack and effectively protects the safety of the items stored in the backpack.

[0055] The top of the first upper cover 130 is provided with a second magnetic groove 130a, and a second magnetic metal sheet is glued to the bottom of the inner side of the second magnetic groove 130a. A handle 130b is sewn on the top surface of the first upper cover 130 to facilitate lifting the backpack.

[0056] The second upper cover 140 covers the top of the first upper cover 130 at the position corresponding to the second magnetic groove 130a, and the bottom surface of the second upper cover 140 at the position corresponding to the second magnetic groove 130a is glued with the second electromagnet 140a.

[0057] The second electromagnet 140a is matched with the second magnetic slot 130a. The second electromagnet 140a is inserted into the inner side of the second magnetic slot 130a and contacts the second magnetic metal sheet. After the second electromagnet 140a is energized and magnetized, it attracts the second magnetic metal sheet and fixes the second electromagnet 140a to the inner side of the second magnetic slot 130a. Through the cooperation of the second electromagnet 140a and the second magnetic metal sheet, the first top cover 130 and the second top cover 140 are fixed together to seal the top opening of the bag body 110. Due to the strong magnetic attraction, without demagnetization, a small external force cannot separate the first top cover 130 and the second top cover 140. At the same time, since the second electromagnet 140a is inserted into the inner side of the second magnetic slot 130a and contacts the first magnetic metal sheet, even a sharp object cannot pry it open between the second electromagnet 140a and the second magnetic metal sheet. This effectively improves the anti-theft performance of the backpack and effectively protects the safety of the items stored in the backpack.

[0058] The power switch 200 is installed on the back of the package 110 at a position corresponding to the first conductive sheet 110b. The power switch 200 includes a fixing plate 210, a spring 220, and a second conductive sheet 230.

[0059] The fixing plate 210 is detachably installed in the mounting hole on the back of the package 110. One side of the fixing plate 210 faces outward, and the other side of the fixing plate 210 faces inward and corresponds to the first conductive sheet 110b.

[0060] One end of the spring 220 is welded to the fixing plate 210, and the side facing the inside of the mounting hole corresponds to the first conductive piece 110b but does not contact the first conductive piece 110b.

[0061] The second conductive piece 230 is detachably mounted on the side of the spring 220 away from the fixing plate 210. The second conductive piece 230 and the spring 220 are electrically insulated from each other. The second conductive piece 230 is located inside the mounting hole. Under the elastic force of the spring 220, the second conductive piece 230 contacts and is electrically connected to the first conductive piece 110b. The second conductive piece 230 is electrically connected to the first electromagnet 120a and the second electromagnet 140a respectively through wires. The power supply to the first electromagnet 120a and the second electromagnet 140a is switched on and off by the connection and disconnection between the second conductive piece 230 and the first conductive piece 110b. When the second conductive piece 230 is connected to the first conductive piece 110b, the first electromagnet 120a and the second electromagnet 140a are energized and magnetized. When the second conductive piece 230 is disconnected from the first conductive piece 110b, the first electromagnet 120a and the second electromagnet 140a are de-energized and demagnetized.

[0062] A third magnetic metal sheet is embedded on the side of the second conductive sheet 230 facing the fixing plate 210, and the third magnetic metal sheet and the second conductive sheet 230 are electrically insulated from each other.

[0063] The back panel assembly 300 is detachably connected to the bag body 110. The back panel assembly 300 includes a back panel 310. A connecting groove is provided on the side wall of the back panel 310. The connecting groove corresponds to the fixing plate 210. A magnetic key 310a is detachably installed in the connecting groove. The magnetic key 310a is a magnet. The magnetic strength of the magnetic key 310a is just enough to overcome the elastic strength of the spring 220 and the strength of the electromagnetic attraction between the first conductive sheet 110b and the second conductive sheet 230.

[0064] When the magnetic key 310a is placed in the connecting slot, it attracts the third magnetic metal sheet. The magnetic force of the magnetic key 310a overcomes the elasticity of the spring 220 and the strength of the electromagnetic attraction between the first conductive sheet 110b and the second conductive sheet 230, causing the second conductive sheet 230 to move towards the side of the fixed plate 210, thus separating the second conductive sheet 230 from the first conductive sheet 110b. This disconnects the power supply to the first electromagnet 120a and the second electromagnet 140a, de-energizing the first electromagnet 120a and the second electromagnet 140a.

[0065] When the magnetic key 310a is removed from the connecting slot, it eliminates the attraction to the second conductive sheet 230. Under the elastic force of the spring 220, the second conductive sheet 230 contacts the first conductive sheet 110b, connecting the power supply to the first electromagnet 120a and the second electromagnet 140a. The first electromagnet 120a and the second electromagnet 140a are energized and generate magnetism.

[0066] Example 3

[0067] Please see Figure 1 and Figure 9 The backpack component 100 also includes shoulder straps 150, and there are two shoulder straps 150, which are sewn onto the left and right sides of the back of the bag body 110 respectively. The bag body 110 is worn on the back of the human body through the shoulder straps 150.

[0068] The backplate assembly 300 also includes a base plate 320 and a chest strap 330;

[0069] The base plate 320 is integrally formed at the bottom of the back plate 310. The back plate 310 and the base plate 320 form an L-shaped structure. The package 110 is placed in the semi-enclosed space of the L-shaped structure formed by the back plate 310 and the base plate 320. The package 110 is detachably connected to the back plate 310 and the base plate 320. The back plate 310 and the base plate 320 support the package 110.

[0070] A groove matching the curvature of the human back is provided on the side of the back panel 310 away from the bag body 110;

[0071] There are two chest straps 330, one on the left and one on the right, hinged to the left and right sides of the back plate 310. The end of the chest strap 330 away from the back plate 310 is detachably equipped with a buckle. One of the two chest straps 330 is equipped with a male buckle and the other is equipped with a female buckle. The two chest straps 330 are connected by the male and female buckles.

[0072] Specifically, when carrying the backpack on the back, the back panel assembly 300, together with the backpack assembly 100, is worn on the back. The back panel 310 is located between the bag body 110 and the back of the human body. The groove on the back panel 310 fits against the back of the human body. The junction of the back panel 310 and the bottom plate 320 abuts against the waist of the human body to support the back panel assembly 300. The shoulder straps 150 are worn on the shoulders, and the chest strap 330 is wrapped around the ribs of the human body and tied together in front of the chest to fix the back panel 310 to the back. The chest, shoulders, and waist of the human body respectively bear the weight of the chest strap 330, the shoulder straps 150, and the junction of the back panel 310 and the bottom plate 320, thus distributing the weight of the backpack to the chest, shoulders, and waist of the human body. Compared with traditional backpacks that concentrate all the weight on the shoulders, this application distributes the weight of the backpack to the chest, shoulders, and waist of the human body, reducing the burden on the shoulders and improving comfort.

[0073] Example 4

[0074] Both the bag body 110 and the front pocket 120 are composed of an inner layer, a middle layer, and an outer layer. The outer layer is made of stab-resistant material found in existing stab-resistant vests, the middle layer is made of shock-absorbing rubber material, and the inner layer is made of soft silicone material. The stab-resistant effect of the outer layer can effectively prevent stabs and cuts, avoid violent damage, and further improve the anti-theft performance of the backpack. The shock-absorbing material and silicone material of the middle and inner layers can effectively protect the items inside the backpack and prevent damage to the items inside the backpack caused by external impacts.

[0075] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
